Create Dymano geometry from autocad ellipse object(s)

Hello

I am new in Dynamo.
I am trying to bring ellipse geometry from autocad/civil3d to dynamo but did not find any suitable node.
After importing ellipse geometry to dynamo of course would like to continue with ellipse’s center, radii, area etc…
Could you suggest any package to me?

Thank you

1 way
convert an ellipse to a polyline
2 way
Use api .net to read properties of ellipse
Then into dynamo geometry
